"\emph{Great things are not done by impulse, but by a series of small things brought together}" [Vincent van Gogh]

Development of iSquirrel involved a lot of planning, wise choice of technologies, careful analysis \& design, refactoring and of course the unavoidable: bug fixing. This chapter describes how our team worked in order to develop this high quality product and explains in detail the major modules of the project:

\begin{itemize}
  \item \textbf{Profiler} - What do we know about the user?
  \item \textbf{Recommender} - How do we recommend articles, video and music?
  \item \textbf{Community} - How do you find friends and how do we recommend you something based on the community?
  \item \textbf{Feedback} - How do we know what the user likes?
\end{itemize}

Apart from the major modules, this chapter describes the revolutionary cross-browser \emph{Poppix} bookmarklet and the design of our simplistic Graphical User Interface.
